|Caste And Color - Veeraswamy Krishnaraj|
Caste is an age-old institution in India. After independence, there has been a social upward mobility of the lower castes, defying the Varna Dharma, which kept the lower castes stultified. Siva and Parvati play the role of Chandala and Chadalini to bring home the point there is no place for caste in Hinduism.

|Space Shuttle: Emphasis for the 1970's - NON|
The space shuttle is described as a vehicle which combines the advantages of airplanes and spacecraft, capable of repeatedly flying to space and back to earth. It will takeoff vertically, powered by two solid propellant boosters, which will be parachuted to earth at an altitude of about 40 km, for retrieval. New uses of space flight are anticipated as costs decrease, turn-around times shorten, and operations simplified...
